"pre filling" oil filter

Re: "pre filling" oil filter

The first time you get a "report" (rattle) from your bearings on startup, after changing the oil, you'll understand. Older high mileage engines will let you know real quick.

What Gerard said.

Thanks.

Re: "pre filling" oil filter

I also believe that it is a good idea to prefill an oil filter and I always do it when it when possible, but do not think it is absolutely necessary.

What about this ? Rather than pre-fill, I've (not always) disconnected the coil HT wire, and held the key in the start position until the pressure slowly comes up. Even better, if your oil change is part of a tune-up and the plugs are removed for cleaning/gapping, the engine spins really fast, as no compression forces on the rod journals.

I'm with Wayne on this for older Chev engines with the canister oil filters. Easy to do and not messy. Pete

The VAST majority of engine wear occurs on start-up. So, to me, anything that might reduce engine wear on start-up is worthwhile.

Re: "pre filling" oil filter

Adding my two cents worth. You mean it can be put on dry? Why? A full filter on initial start up reduces the space the return oil has to fill before going back to the pan. Besides, like everyone else said, that's the way my dad taught me.

Re: "pre filling" oil filter

I have always filled up the filters at least 3/4 full. Don't forget to put a little oil on the gasket.
Diesel engines have to have the fuel filters full. The injectors need fuel pressure immediately. If they get air, your done, it will not start.
I along with a host of other long time guy's, had their Dad's show us how to fill the oil canister just for safety wear on the engine.

It's actually COLD starts and warmup. Hot starts - say within an hour of shutdown in mild temperatures - are no big deal.
